People with Parkinson’s don’t have enough of 
a chemical called dopamine, because some of the 
nerve cells in their brain that make it have died.
Although there’s currently no cure for Parkinson’s, 
a range of drugs, treatments and therapies are 
available to manage many of the symptoms caused 
by the lack of dopamine in the body.
Dopamine agonist drugs act like dopamine to 
stimulate nerve cells. 
Apomorphine is a strong 
dopamine agonist.
Unlike other dopamine agonist drugs, which 
are taken as tablets or patches, apomorphine 
is taken by intermittent injection or via infusion, 
using a pump.
There is no link between apomorphine and the 
pain-killing drug morphine
